PIN FUNCTIONS
SENSE1+, SENSE2+: Positive Inputs to the Current
Comparators. The ITH pin voltage programs the current
comparator offset in order to set the peak current trip
threshold. This pin is normally connected to a sense
resistor in the source of the power MOSFET.
SENSE1, SENSE2:
Negative Inputs to the Current Com-
parators. This pin is normally connected to the bottom of
the sense resistor.
SGND: Signal Ground. All feedback and soft-start con-
nections should return to SGND. For optimum load
regulation, the SGND pin should be kelvin connected to
the PCB location between the negative terminals of the
output capacitors.
SLOPE: This pin programs the gain of the internal slope
compensation. Floating this pin provides a normalized
slope compensation gain of 1.00. Connecting this pin
to 3V8 increases the normalized slope compensation by
66%, and connecting it to SGND decreases the normalized
slope compensation by 37.5%. See Applications Informa-
tion for more details.
SS: Soft-Start Input. For soft-start operation, connecting
a capacitor from this pin to SGND will clamp the output of
the error amp. An internal 5μA current source will charge
the capacitor and set the rate of increase of the peak switch
current of the converter.
SYNC: PLL Synchronization Input. Applying an external
clock between 50kHz and 650kHz will cause the operating
frequency to synchronize to the clock. SYNC is pulled down
by a 50k internal resistor. The rising edge of the SYNC
input waveform will align with the rising edge of GATE1
in closed-loop operation.
VIN: Main Supply Input. A low ESR ceramic capacitor
should be connected between this pin and SGND.
